Sub Zero Heating & Air Conditioning

Sub Zero Heating & Air Conditioning serves residential and commercial clients across Columbus and central Ohio with heating and cooling solutions backed by 161 verified customer reviews averaging 4.7 stars. The company maintains standard business hours from 8 AM to 6 PM seven days a week, making it accessible for scheduling routine maintenance appointments and same-day emergency repairs. Property managers in the Columbus area specifically note the company's responsiveness, with one managing multiple rental properties praising the team's ability to reach a freezing tenant within two hours of the service request.

What distinguishes Sub Zero from other regional contractors is their focus on indoor air quality as a dedicated specialty, addressing ventilation, filtration, and air purification systems rather than treating IAQ as an afterthought. The company provides financing options for customers who need new equipment but prefer to spread costs over time, and promotes maintenance agreements designed to extend system lifespan and reduce monthly utility bills. Commercial HVAC installation and air duct sealing round out their service menu, targeting both homeowners and business owners seeking improved system efficiency.

Customers frequently mention technician Gage by name, noting his ability to assess heat pump replacement needs, explain findings in understandable terms, and complete installation within a week. Another reviewer describes Sub Zero saving their family from over a week without heat after receiving a $4126 estimate from another company, with technicians identifying a specific faulty component rather than recommending full furnace replacement. A third customer praised the team for accessing difficult attic components through a closet, carefully moving and rehanging all clothing before completing repairs.
